Hydrogen fuel cell, one of the main power sources in environmentally benign hydrogen economy, has its own cost and performance limitations which is a large drawback for moving forward with this demanding technology to reduce GHG emissions particularly in the transportation sector from mid-to-heavy duty vehicles. Research on the bipolar plates, a vital component, can be a solution to address this on-going issue which needs improvement in electrical and mechanical attributes. In this dissertation, investigation was carried out on anisotropically distributed advanced functional carbonaceous materials along with the introduction of novel biocarbons which can facilitate to improve the performance of carbon polymer composites by increasing the movement of charged particles through decoupling of repulsion, increased conjugated carbon-carbon aromatic structure and through the spin non-conservation in the crystal lattice structure. The highest electrical conductivity was achieved 221 S/cm and flexural strength 64 MPa, well above the US DOE target of 100 S/cm and 25 MPa respectively. It was observed that the non-destructive porous structure measurement can determine the extent of electrical conductivity. A novel continuous carbon fiber process showed crucial potential in improved mechanical properties with excellent electrical conductivity. The use of multi-fillers and intercalated carbonaceous materials can help to reduce the density, thickness and weight to a large extent which is important for the fabrication of a highly conductive, mechanically flexible and light-weight composite. In this research, a holistic approach of effective intrinsic properties, optimized process parameters and novel functional materials proved to facilitate achieving a high-performance composite for bipolar plates.
